Definitions

  • the present invention relates to the design of electrically insulating intermediate layers between structures in a honeycomb body, in particular an electrically heatable catalyst support body for motor vehicles.
  • catalytic converters are used, in particular also electrically heated catalytic converters to reduce pollutant emissions even in the cold start phase.
  • Electrically heated honeycomb bodies are described in various embodiments, for example in WO 89/10471.
  • electrically heatable honeycomb bodies are equipped with electrically insulating intermediate layers, between which the electric current takes a defined path.
  • electrically heatable honeycomb bodies are also exposed to considerable mechanical loads, in particular thermal alternating loads.
  • the previously known electrically insulating intermediate layers or gaps can generally not absorb strong mechanical tensile forces, which has to be taken into account as a limitation in the design and manufacture of such honeycomb bodies.
  • Honeycomb bodies are also known from WO 89/07488, which have one or more reinforced sheet metal layers, the reinforced sheet metal layers in particular also being able to consist of several sheet metal layers which are structured in a similar manner and lie against one another.
  • the object of the present invention is to provide electrical insulation between structures of such honeycomb bodies, which can be particularly easily integrated into a manufacturing process and can additionally absorb mechanical forces, in particular can also withstand tensile forces. In this way, the structure of electrically heatable honeycomb bodies is to be simplified while increasing the mechanical load capacity.
  • a honeycomb body in particular a catalyst carrier body, made of at least partially structured sheet metal layers, which form a multiplicity of channels through which a fluid can flow, is used to achieve this object, the honeycomb body having an electrically insulating intermediate layer and the intermediate layer having at least two mechanically clamped together but electrically by an insulating layer contains sheet metal layers insulated from one another.
  • two sheet metal layers can be clamped together in spite of electrical insulation in such a way that mechanical tensile forces are absorbed by the clamp and not by the insulation arranged between the sheet metal layers. Clamping is possible here, which react particularly elastically to tensile forces, and others which can absorb large tensile forces without severe deformation.
  • the intermediate layer is designed in such a way that the clamped sheet-metal layers consist largely of metal on both sides and thus on both sides by soldering or the like joining processes with other sheet metal layers can be connected.
  • Sheet metal layers with a ceramic intermediate layer are known from WO 89/10471, which protrude into one another in a form-fitting manner to absorb axial forces, but these sheets are not clamped, so that a tensile load could still tear the sheets apart. This is to be avoided in the present invention while maintaining the possibility of bilateral connection to adjacent sheet metal layers.
  • bracketing As explained in more detail in the drawing with the aid of a few exemplary embodiments, the simplest form of bracketing is that one sheet metal layer encompasses the other sheet metal layer on its side edges. Another, more elastic clamping is that the sheet layers are mutually folded around each other. Shapes in which the sheet metal layers are folded around one another in a form-fitting manner or nested into one another are also possible.
  • one or more electrical conductors which are electrically insulated from the sheet metal layers and which can serve, for example, as temperature sensors between the clamped sheet metal layers.
  • a linear or flat temperature sensor can be integrated into the honeycomb body without considerable additional installation work, which is particularly advantageous for the regulation of heatable catalytic converters.
  • clamped sheet-metal layers As a smooth intermediate layer, but as a structured, in particular corrugated, intermediate layer. In this way, a greater flexibility of the intermediate layer is achieved than with one of several Layers of existing smooth intermediate layer is possible.
  • the production of clamped sheet metal layers is particularly easy by rolling. In this way, the pre-folded sheet metal layers provided with an insulating layer can be rolled between a pair of rollers to reduce the thickness of the intermediate layer. In particular, rolling between corrugated rolls, as are well known for the structuring of sheets for honeycomb bodies, is also possible without problems.
  • the other sheet metal layers of the honeycomb body adjoining the clamped sheet metal layers are shortened to the extent that the clamping of one sheet metal layer encompasses the other sheet metal layer.
  • face soldering can be carried out as usual, only the connection between the shortened sheet metal layers and the intermediate layer having to be made separately, for example by inserting solder foils.
  • the outer surfaces of the clamped sheet metal layers are joined, preferably brazed, in the same way with adjacent other sheet metal layers, as is also the case between the other sheet metal layers.
  • FIG. 1 shows a perspective cross section through an insulating intermediate layer according to the invention made of smooth sheet metal layers
  • FIG. 2 shows a corrugated intermediate layer with integrated temperature sensors
  • FIG. 3 shows a smooth intermediate layer with an additional integrated conductor
  • FIGS. 4, 5 and 6 different types of clamps
  • FIG. 7 shows a clamp form with an additional integrated electrical conductor
  • 8 shows the integration of an intermediate layer projecting beyond the end faces of a honeycomb body
  • 9 shows the incorporation of an intermediate layer which does not protrude beyond the end faces of the honeycomb body.
  • FIG. 1 shows a cross section through the simplest embodiment of the present invention, in which a smooth sheet metal layer 11 is separated from a smooth sheet metal layer 12 by an insulating layer 14.
  • FIG. 2 shows that intermediate layers according to the invention can also preferably be of corrugated form, a sheet layer 21 being in turn separated from another sheet layer 22 by an insulating layer 24. Clamping between the two sheet metal layers 21, 22 can in turn take place by bending the outer edges 23 of the sheet metal layer 22, as is indicated by the dashed lines as folded edge 28.
  • the clamping 23 by soldering on additional parts, for example a solder foil 25 being inserted and rolled in, which then establishes a firm connection during a later soldering process. Inserting the solder foil 25 can also be advantageous when using folded edges 28, since sharp folded edges 28 can possibly become brittle and then cannot guarantee the desired function, namely to absorb tensile forces.
  • two sheathed measuring conductors 26, 27 are additionally integrated into the brackets, which is easily possible in the arrangement shown laterally next to the sheet metal layer 21.
  • FIG. 3 shows another variant for integrating an additional electrical conductor 36 between two clamped sheets 31, 32.
  • an additional insulating layer 35 is required.
  • FIGS. 4, 5, 6 and 7 schematically show, in cross-section, examples of different forms of clamping, the insulating layers not being shown.
  • the representation is not to scale either, since after rolling a total of an intermediate layer of, for example, only 0.1 to 1 mm.
  • Figure 4 shows an elastic type of clamping, in which two sheet metal sides are mutually folded around each other. This type of clamping reacts very elastic to train, but without the layers can be torn apart.
  • FIG. 5 shows two sheet layers 51, 52 folded several times around, the arrangement there also reacting very elastically to train, but is additionally secured against parallel displacement in any direction.
  • FIG. 6 shows a stapling in which a sheet-metal layer 62 encompasses an approximately omega-shaped second sheet-metal layer 61.
  • two sheet metal layers 71, 72 and an additional electrical conductor 76 are clamped together in a special way.
  • the electrical conductor 76 encompasses the one sheet metal layer 71.
  • the sheet metal layer 72 jointly encompasses both layers 71 and 76.
  • FIGS. 8 and 9 show possible incorporations of intermediate layers according to the invention in a honeycomb body.
  • FIG. 8 shows a variant in a schematic longitudinal section through part of a honeycomb body, in which the electrically insulating intermediate layer projects on both sides beyond the end faces of the honeycomb body.
  • the other sheet-metal layers 84, 85 of the honeycomb body are soldered on the outside to the sheet-metal layers 81 and 82, respectively, with the clipping 83 over the end faces of the honeycomb body thus formed protrudes.
  • the honeycomb body 90 consists of structured sheet metal layers 97 which form channels 98 which are permeable to a fluid in a known manner.
  • Different segments 95, 96 of the honeycomb body 90 are electrically insulated from one another by the insulating intermediate layer 91, 92, 93, 94, the sheet metal layer 92 being soldered directly to the other sheet metal layers 97 of the segment 96, while the connection to the segment 95 is shortened by adjacent ones Sheet layers 99 takes place.
  • the intermediate layer 91, 92, 93, 94 consists of smooth sheet metal layers
  • the adjacent sheet metal layer 99 is a shortened corrugated sheet metal layer.
  • the intermediate layer itself is corrugated, u. U. connect two shortened structured sheet metal layers in order to avoid a short circuit at the brackets 93.
  • intermediate layers according to the invention can be produced by rolling in practically any desired structure, in particular as smooth layers, corrugated layers, obliquely corrugated layers, with arrow-shaped corrugation, etc.
  • the incorporation of intermediate layers according to the invention in a manufacturing process can be quite analogous in many embodiments to the methods described in WO 89/07488 and the documents cited therein, where it may only be necessary to take into account that there are no short circuits in the area of the brackets.
  • the present invention is particularly suitable for the production of electrical insulation in electrically heatable catalyst carrier bodies for motor vehicles.
